Directional conductance of Andreev crystals in hybrid Josephson junction arrays
Anders Enevold Dahl, Andrea Maiani, Max Geier +2
Andreev bound states are coherent electron-hole superpositions that form in a normal metal through repeated Andreev reflection at a superconducting interface. When the length of a…
Fermion-parity qubit in a proximitized double quantum dot
Max Geier, Rubén Seoane Souto, Jens Schulenborg +3
Bound states in quantum dots coupled to superconductors can be in a coherent superposition of states with different electron number but with the same fermion parity. Electrostatic…
Non-Abelian holonomy of Majorana zero modes coupled to a chaotic quantum dot
Max Geier, Svend Krøjer, Felix von Oppen +3
If a quantum dot is coupled to a topological superconductor via tunneling contacts, each contact hosts a Majorana zero mode in the limit of zero transmission. Close to a resonance…
Conductance matrix symmetries of multiterminal semiconductor-superconductor devices
Andrea Maiani, Max Geier, Karsten Flensberg
Nonlocal tunneling spectroscopy of multiterminal semiconductor-superconductor hybrid devices is a powerful tool to investigate the Andreev bound states below the parent superconduc…
Higher-order topological semimetals and nodal superconductors with an order-two crystalline symmetry
Sophia Simon, Max Geier, Piet W. Brouwer
Using a systematic relation between topological gapless phases in three dimensions and topological gapped phases in two dimensions, we identify four types of higher-order topologic…
Identifying Majorana vortex modes via non-local transport
Björn Sbierski, Max Geier, An-Ping Li +3
The combination of two-dimensional Dirac surface states with s-wave superconductivity is expected to generate localized topological Majorana zero modes in vortex cores. Putative ex…
